Chandra X-Ray Observatory Observations of 13 Fermi LAT Sources

The Astrophysical Journal
In the latest data release from the Fermi Gamma-ray Space Telescope (the 4th Fermi LAT 14 yr Catalog, or 4FGL), more than 50% of the Galactic sources are yet to be identified.

Sixteen Years of Gamma-Ray Discoveries and AGN Observations with Fermi-LAT

Particles
In June 2024, the Fermi Gamma-Ray Space Telescope (FGST) celebrated its 16th year of operations. The Fermi Large Area Telescope (Fermi-LAT) is the main instrument onboard the FGST satellite and is designed to be sensitive to γ-rays in the energy range ...

Fermi Unassociated Sources in the MeerKAT Absorption Line Survey

The Astrophysical Journal
Over 2000 γ -ray sources identified by the Large Area Telescope on NASA's Fermi Gamma-ray Space Telescope are considered unassociated, meaning that they have no known counterparts in any other frequency regime.

Time-averaging Polarimetric and Spectral Properties of Gamma-Ray Bursts

The Astrophysical Journal Supplement Series
The composition and radiation mechanism of gamma-ray bursts (GRBs) within jets continue to be hotly debated. Investigating the joint polarimetric and spectral properties is crucial for understanding the composition and radiation mechanism of GRBs ...
